Below are a few points that will help to interpret the maps on the website.

Each circle or dot on the map represents a
station.

The legenda on the right of the map indicates what the
colours mean. For example, on a trend map for precipitation
amount, blue circles indicate a wetting trend while red circles
indicate a drying trend.

On the trend and anomaly maps, the size of the circle gives a
range for the size of the trend of that particular station.

Using the i-button and clicking on a station will give a
pop-up with details of that station, including the value of the
trend or anomaly, depending on the map.

The station density varies over Europe. This indicates that
stations with data series available for the requested time period
are not equally distributed over Europe. In some areas there are
fewer stations or fewer stations which exist for a long time
period. In other areas the ECA&D team does not have access to
all available station series (often due to data policy
differences between countries). Zooming in will make it possible to
distinguish between different stations.
